Bike Shock Pumps — Set Your Suspension, Ride Better

Suspension pressure is one of the most impactful and most overlooked tuning variables on any mountain bike. Too much air and your fork or rear shock rides harsh, skipping over roots and rocks instead of absorbing them. Too little and you bottom out, lose control, and waste energy. A quality shock pump gives you the precision to dial in your suspension exactly — and keep it there. Read our guide on Mountain Bike Suspension: Top Things to Know to understand why pressure matters and how to set it correctly.

This collection features the B2BF High Pressure Shock Pump range — capable of up to 300 PSI, built for both air forks and rear air shocks, and precise enough to make meaningful adjustments in single-PSI increments. Whether you're setting up a new MTB, fine-tuning your SE:Series hardtail, or maintaining your suspension between rides, these pumps are the tool for the job.

Shock Pumps in This Collection

B2BF High Pressure 300 PSI Shock Pump — Black

The workhorse of the B2BF pump range. 300 PSI maximum pressure covers the full range of air forks and rear shocks on the market — from lightweight XC forks running 60–80 PSI to high-volume enduro shocks requiring 200+ PSI. A precision gauge, bleed valve for fine pressure release, and a compact form factor make this the ideal pump for home workshop and trailhead use alike.

B2BF High Pressure 300 PSI Shock Pump — Lime

Identical performance to the Black model in a high-visibility Lime colourway — easy to spot in a workshop or kit bag, and a great match for riders who colour-coordinate their accessories. Same 300 PSI capacity, same precision gauge, same bleed valve.

How to Use a Shock Pump

Check your fork/shock manufacturer's recommended pressure range — this is usually found in the manual or on a sticker on the fork leg
Connect the pump to the Schrader valve on your fork or rear shock — thread it on firmly to avoid air loss
Read the current pressure before adding or releasing air
Adjust in small increments — 5 PSI changes make a noticeable difference; use the bleed valve to release air precisely
Test on the trail — aim for 25–30% sag as a starting point and adjust from there

Frequently Asked Questions

What is a shock pump and why do I need one?

A shock pump is a high-pressure pump specifically designed for inflating air suspension forks and rear shocks on mountain bikes. Unlike a standard floor pump, a shock pump has a small-volume, high-pressure barrel capable of reaching 300 PSI or more, and a precision gauge for accurate readings. You need one to set and maintain correct suspension pressure — which directly affects how your bike handles, how much control you have, and how comfortable your ride is.

Can I use a regular floor pump on my suspension?

No. Standard floor pumps are not designed for the high pressures required by air suspension and will not read or deliver pressure accurately in the 50–300 PSI range. Always use a dedicated shock pump for suspension setup. See our MTB Suspension Guide for more detail.

What PSI should I run in my fork?

Fork pressure varies by rider weight, fork model, and riding style. Most manufacturers provide a pressure chart based on rider weight — check your fork's manual or the sticker on the fork leg. As a general starting point, aim for 25–30% sag: compress the fork with your body weight in riding position and measure how far it travels. Adjust pressure until sag is in the correct range.

Does the B2BF pump work with both forks and rear shocks?

Yes. The B2BF 300 PSI pump is compatible with standard Schrader valves used on the vast majority of air forks and rear shocks. Always check your specific suspension unit's valve type before purchasing — some older or specialist units use proprietary valves.

How often should I check my suspension pressure?

Air suspension loses pressure gradually over time — check and adjust at least once a month, and always after a long break from riding or a significant change in temperature. Cold weather reduces air pressure; warm weather increases it. Regular checks keep your suspension performing consistently.
